TECHNICAL FIELD

The present invention relates to an electronic cigarette, in particularto an electronic atomization cigarette that contains only nicotinewithout tar.

BACKGROUND ART

Despite it is commonly known that “smoking is harmful to your health”,the number of smokers worldwide is up to 1 billion, and the number isincreasing every year. On Mar. 1, 2003, the World Health Organization(WHO) concluded a global Framework Convention on Tobacco Control.According to the statistical data from WHO, about 4.9 million people dieof is diseases caused by smoking each year. Although smoking may causeserious respiratory diseases and cancer, it remains extremely difficultfor smokers to quit smoking completely.

The active ingredient in a cigarette is nicotine. During smoking,nicotine, along with a lot of tar aerosol droplets produced in thecigarette burning, enters smoker's alveolus and is rapidly absorbed.After being absorbed into the blood of a smoker, nicotine then producesits effect on the receptors of the smoker's central nervous system,which makes him/her relax and enjoy an inebriety similar to thatproduced by an exhilarant.

Nicotine is a kind of alkaloid with low molecular weight, a small doseof nicotine is essentially harmless to human body and its half-life inblood is quite short. Actually the major harmful substance in tobacco istar, tar in tobacco is composed of thousands of ingredients, tens ofwhich are cancerogenic substances. At present it has been proven thatpassive smoking can be more harmful on non-smokers.

Some cigarette substitutes flat contain only nicotine without tar havebeen proposed, many of them, such as “nicotine patch”, “nicotinemouthwash”, “spray agent packaged in high pressure gas tank withpropellant”, “nicotine chewing gum”, “nicotine drink” etc., are made ofpure nicotine. Although these cigarette substitutes are free from tar,their major disadvantage is that an effective peak concentration can notbe reached in the blood of a smoker due to slow absorption of nicotineand thus it can not make a smoker get real fin, in addition, thesecigarette substitutes can not satisfy habitual smoking actions of asmoker, for example, inhaling action or sucking action, and thus are notlikely to be widely accepted as effective substitutes for quittingsmoking or cigarette substitutes.

The short stream ejectionhole 30 has the diameter of about 0.3 mm-1.3 mm. The atomization cavitywall 25 is surrounded with the porous body 27, which can be made of foamnickel, stainless steel fiber felt, high molecule polymer foam and foamceramic. A first piezoelectric element 23 is also provided on theatomizer 9. The atomization cavity wall 25 can be made of aluminum oxideor ceramic. As shown in FIG. 9, a through hole is provided on thevapor-liquid separator 7, and can be made of plastic or silicon rubber.As shown in FIG. 11, a retaining ring 13 for locking theliquid-supplying bottle 11 is provided between one side of theliquid-supplying bottle 11 and the shell 14, an aerosol passage 12 isprovided on the other side of the liquid-supplying bottle. The solutionstorage porous body 28 is provided in the liquid-supplying bottle, andcan be filled with polypropylene fiber, terylene fiber or nylon fiber,or be filled with plastic that are shaped by foaming, such as polyamineresin foam column or polypropylene foam column; alternatively, it may bemade of a column formed by molding polyvinyl chloride, polypropylene,polycarbonate into a stack of laminated layers.

The operatingprinciple of the circuit is as follows: when K1 is closed, U1, i.e., thefield effect power transistor, is turned on, RL starts, and the Colpittsoscillator starts oscillating, M1 will provide the high frequencymechanical oscillatory wave to the atomizer 9 to achieve the result ofatomization.

When a smoker smokes, the mouthpiece 15 is under negative pressure, theair pressure difference or high speed stream between the normal pressurecavity 5 and the negative pressure cavity 8 will cause the sensor 6 tooutput an actuating signal, the electronic circuit board 3 connectedtherewith goes into operation. Now the ripple film 22 in the sensor 6 isdeformed to take the second magnetic steel 21 away from the Reed switch19, and the Reed switch 19 is then closed (i.e., K1 is closed) under theeffect of the excessive magnetic line of force from the first magneticsteel 20, starting the field effect power transistor electronic switch(i.e., U1 is opened). The high frequency oscillator may uses theColpitts oscillator with the frequency of 550 KHz-8 MHz, the automaticfine-adjusting element in the circuit resonates with the firstpiezoelectric element 23 in the form of a ring to supply power to liquidmolecule, and the LED 1 can be lit under the supply of the rechargeablebattery 2. The air enters the normal pressure cavity 5 through the airinlet 4, passes through the air passage 18 of the sensor and then thethrough hole in the vapor-liquid separator 7, and flows into theatomization cavity 10 in the atomizer 9. The high speed stream passingthrough the ejection hole drives the nicotine solution in the porousbody 27 to eject into the atomization cavity 10 in the form of droplet,where the nicotine solution is subjected to the ultrasonic atomizationby the first piezoelectric element 23 and is further atomized by theheating element 26. After the atomization the droplets with 35 largediameter stick to the wall under the action of eddy flow and arereabsorbed by the porous body 27 via the overflow hole 29, whereas thedroplets with small diameter float in stream and forms aerosols, whichare sucked out via the aerosol passage 12, gas vent 17 and mouthpiece15. The solution storage porous body 28 in the liquid-supplying bottle11 will be in contact with the bulge 36 on the atomizer 9, therebyachieving the capillary infiltration liquid-supplying.

The mouthpiece 15 is threaded. When the nicotine solution in theliquid-supplying bottle 11 is used up, users can screw the mouthpiece 15out to take the liquid-supplying bottle 11 out, refill theliquid-supplying bottle 11 with the nicotine solution, put theliquid-supplying bottle 11 into the shell 14 again, and then screw themouthpiece 15.

The Reed switch 19, the first magnetic steel 20, the second magneticsteel 21, the ripple film 22 can be replaced by a semiconductor straingauge with sealed film, which is mounted in the place of the sensorripple film.

To simplify the design, the first piezoelectric element 23 on theatomizer 9 can be omitted, and the atomization of the nicotine solutionwill be made only by the heating element 26. The size of such anatomizer can be made smaller, and the structure of the connection of thewhole electronic atomization cigarette is the same as the embodiment 1.In addition, as shown FIG. 8, the first piezoelectric element 23 and theheating element 26 in the atomizer 9 can be omitted, an additionalsecond piezoelectric element 35 in the form of platen with a singlelayer or multiple laminated layers can be arranged in the atomizationcavity, and the stream passing through the ejection hole vibrates thefocus at the center of the second piezoelectric element 35 to achievethe effect of strong ultrasonic atomization.
